Efficacy—Overall survivalThe first and only FDA-approved targeted therapy regimen for adults with previously treated mCRC with a BRAF V600E mutation1-5Superior overall survival with BRAFTOVI + cetuximab vs controlOverall survival—Primary analysis

  • Cutoff date for primary analysis was February 11, 2019. Median duration of follow-up for OS was 7.8 months6
Post hoc updated OS analysis with BRAFTOVI + cetuximab and control7*The OS update is a post hoc analysis and should be interpreted in the context of this limitation. No conclusions regarding efficacy may be drawn.References
  • Median OS was 9.3 months (95% CI: 8.0-11.3) with BRAFTOVI + cetuximab and 5.9 months (95% CI: 5.1-7.1) with FOLFIRI + cetuximab or irinotecan + cetuximab (HR=0.61 [95% CI: 0.48-0.77])
  • Number of OS events: 128 (58%) with BRAFTOVI + cetuximab and 157 (71%) with FOLFIRI + cetuximab or irinotecan + cetuximab
  • Cutoff date for post hoc updated OS analysis was August 15, 2019. Median duration of follow-up for OS was 12.8 months

PP-BRA-USA-0232
INDICATION AND USAGE

BRAFTOVI® (encorafenib) is indicated, in combination with cetuximab, for the treatment of adult patients with metastatic colorectal cancer (CRC) with a BRAF V600E mutation, as detected by an FDA-approved test, after prior therapy.
 

Limitations of Use: BRAFTOVI is not indicated for treatment of patients with wild-type BRAF CRC.​​​​​​​

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS


New Primary Malignancies, cutaneous and non-cutaneous, can occur with BRAFTOVI. In the BEACON CRC trial, cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 1.4% of patients with CRC, and a new primary melanoma occurred in 1.4% of patients who received BRAFTOVI in combination with cetuximab. Perform dermatologic evaluations prior to initiating treatment, every 2 months during treatment, and for up to 6 months following discontinuation of treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Dose modification is not recommended for new primary cutaneous malignancies. Based on its mechanism of action, BRAFTOVI may promote malignancies associated with activation of RAS through mutation or other mechanisms. Monitor patients receiving BRAFTOVI for signs and symptoms of non-cutaneous malignancies. Discontinue BRAFTOVI for RAS mutation-positive non-cutaneous malignancies.

Tumor Promotion in BRAF Wild-Type Tumors: In vitro experiments have demonstrated paradoxical activation of MAP-kinase signaling and increased cell proliferation in BRAF wild-type cells exposed to BRAF inhibitors. Confirm evidence of BRAF V600E or V600K mutation using an FDA-approved test prior to initiating BRAFTOVI. 

Hemorrhage: In BEACON CRC, hemorrhage occurred in 19% of patients receiving BRAFTOVI in combination with cetuximab; Grade 3 or higher hemorrhage occurred in 1.9% of patients, including fatal gastrointestinal hemorrhage in 0.5% of patients. The most frequent hemorrhagic events were epistaxis (6.9%), hematochezia (2.3%), and rectal hemorrhage (2.3%). Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction.

Uveitis: Uveitis, including iritis and iridocyclitis, has been reported in patients treated with BRAFTOVI. Assess for visual symptoms at each visit. Perform an ophthalmological evaluation at regular intervals and for new or worsening visual disturbances, and to follow new or persistent ophthalmologic findings. Withhold, reduce dose, or permanently discontinue based on severity of adverse reaction.

QT Prolongation: BRAFTOVI is associated with dose-dependent QTc interval prolongation in some patients. Monitor patients who already have or who are at significant risk of developing QTc prolongation, including patients with known long QT syndromes, clinically significant bradyarrhythmias, severe or uncontrolled heart failure and those taking other medicinal products associated with QT prolongation. Correct hypokalemia and hypomagnesemia prior to and during BRAFTOVI administration. Withhold, reduce dose, or permanently discontinue for QTc >500 ms.

Embryo-Fetal Toxicity: BRAFTOVI can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with BRAFTOVI and for 2 weeks after the final dose. Advise females to contact their healthcare provider of a known or suspected pregnancy.

Lactation: Advise women not to breastfeed during treatment with BRAFTOVI and for 2 weeks after the final dose.

Infertility: Advise males of reproductive potential that BRAFTOVI may impair fertility.

Risks Associated with Combination Treatment: BRAFTOVI is indicated for use as part of a regimen in combination with cetuximab. Refer to the prescribing information for cetuximab for additional risk information.

ADVERSE REACTIONS

The most common adverse reactions (≥25%, all grades) in the BRAFTOVI with cetuximab arm compared to irinotecan with cetuximab or FOLFIRI with cetuximab (control) were: fatigue (51% vs 50%), nausea (34% vs 41%), diarrhea (33% vs 48%), dermatitis acneiform (32% vs 43%), abdominal pain (30% vs 32%), decreased appetite (27% vs 27%), arthralgia (27% vs 3%), and rash (26% vs 26%). Other clinically important adverse reactions occurring in <10% of patients who received BRAFTOVI in combination with cetuximab was pancreatitis.

The most common laboratory abnormalities (≥20%, all grades) in the BRAFTOVI with cetuximab arm compared to irinotecan with cetuximab or FOLFIRI with cetuximab (control) were: anemia (34% vs 48%) and lymphopenia (24% vs 35%).

DRUG INTERACTIONS

Avoid coadministration of BRAFTOVI with strong or moderate CYP3A4 inhibitors (including grapefruit juice) or CYP3A4 inducers and use caution with sensitive CYP3A4 substrates. Avoid coadministration of BRAFTOVI with hormonal contraceptives.

Modify BRAFTOVI dose if coadministration with a strong or moderate CYP3A4 inhibitor cannot be avoided.

Avoid coadministration of BRAFTOVI with drugs known to prolong QT/QTc interval.

Dose reductions of drugs that are substrates of OATP1B1, OATP1B3, or BCRP may be required when used concomitantly with BRAFTOVI.

Refer to the cetuximab prescribing information for recommended dosing and safety information.
